We must allow the word of God to correct misconceptions. Blind faith is not going to save anyone. The 'liberation' you speak of is not true freedom, but is an excuse for not making a thorough investigation. (1 Pet 3:15)
In Luke 17:21, Jesus was telling those Pharisees that he, as king of God's Kingdom was standing there right in their midst, yet they refused to recognize him.
The kingdom is an "administration" used by God to reconcile the sinful human race back into an acceptable relationship with himself. It is headed by Jesus Christ and 144,000 chosen from the earth to assist him as kings and priests. (Eph 1:9-12; Rev 14:3; 20:6)
Luke 17:21 is not saying what many have been taught. It is a false assumption based on inaccurate knowledge of the scriptures.
Please reconsider. The Bible interprets itself if you let it. Remember that Jesus preached a different message to what those Pharisees were teaching. The people had to decide whether to stick with a long entrenched tradition or listen to the truth Jesus preached and change their beliefs accordingly. It meant being different and looked down upon.
Look at the attitude of the people when Pilate offered to release Jesus....read Matt 27:22-25. Who led the people to adopt that attitude?
Christendom is the modern counterpart of the Judaism of Jesus' day. They too have preferred their traditions over the word of God. Read what Jesus said about those Jewish traditions taught by the Pharisees in Matt 15:6-9.
The court of public opinion has never been favorable to God's true servants and never a reliable source to base such an important decision upon. This is a life and death issue. Don't make your decision by relying on the beliefs held by the "many". (Matt 7:13, 14).
